having rather "XL" wrists from use in other sports, Shot Put, Weight Training, has made it difficult for me to get the full effect of yonkyo, that was until one of my former Sensei decided to let the ENTIRE CLASS try me out for 30 minutes or so at which point he took over and had no problem finding that nerve. We all had a good laugh about it (after I stopped sobbing) and I found a new inspiration for being a better Uke.
